Russia: The giant crater in Siberia is constantly growing at a rate of 20-30 meters per year under the influence of global warming.

Located near the Yana River basin about 660 km northeast of Yakutsk city, Batagaika Crater is one of the largest in the world with a length of 1 km and a depth of 50 meters. However, as the ice in the area is melting rapidly, the craters become deeper at an alarming rate, which could pose a danger of subsidence in nearby settlements.
The Siberian tundra is home to many supermassive hollow holes formed by melting permafrost, but the Batagaika crater attracts even more attention with the nickname “Hell’s Gate” by the locals. put. Sensors that track the crater’s growth show that it expands by 20 to 30 meters per year as the ice melts into water and passes away. Climate change is driving this process, releasing gas and mineral ores that have been buried under ice for thousands of years.
“Ice turns into water, evaporates or leaches away, while uncoated sediment settles down. The result is an uneven surface due to the fluctuating amount of ice in the sediment. From above, Batagaika looks like a stingray that stretches northeast-southwest with a vertical wall of ice nearly 70 meters high on the south-western edge, “said Kseniia Ashastina, researcher at the Max Planck Institute. .
According to professor of geology, Julian Murton of the University of Sussex, “although Batagai has existed through periods of natural warming in the past. From the 1950s to 1960s, human activity caused the ancient permafrost to freeze. This becomes less stable. So we need to be very careful, “Murton said.
Scientists are continuing to monitor the area, watch for warning signs and explore the disintegration of frozen soil to learn more about the past. According to Murton, the results of dating of the bottom layer show that Batagaika crater is about 650,000 years old, the oldest in Eurasian continent and second in the world. Ashastina says studying Batagaika can help scientists determine the relationships between humans, animals, plants and the environment in order to find solutions to climate change.
